Spelling correction of the word "Assohles", I fixed the typo and changed it to "Assholes". I also capitalized the words "French", and "English" in the description section.
I got the following errors when I attempted to submit my corrections so I had to download, resize, and upload/change the images as well:

Intro music plays at the beginning of every Phase instead of the first of every 3 Phases

Phase designs are revisited starting from Phase 1 instead of Phase 4

Custom palette code: each Phase and Bonus Phase has its own unique palette; the original game had different palettes for every 3 Phases

This hack was created as a proof of concept for a Balloon Fight level hack, in contrast to previous Balloon Fight hacks that are primarily graphical hacks.

The level format and basic components of the game have been documented and submitted separately, available for other ROM hackers to potentially create their own awesome Balloon Fight level hacks! Download the collection of documents for Balloon Fight Level Hackinghere.

Due to NROM-128 to NROM-256 ROM expansion, this hack uses the BPS patch format instead of the IPS patch format. Please download the beat utility by byuu and refer to the readme file for appropriate patching instructions.

Give it a play

I got a chance to play Cosmic Balloon Assault today, and here are my thoughts…

It’s the first hack of Balloon Fight that changes the levels. I’m sure it won’t be the last, since Quick Curly also posted a very detailed document explaining where all the game level data is and how to edit them. :)

It’s slightly harder than the original, but makes up for it by giving you many more lives. Some of the later levels have cramped spaces, but this can work to your advantage if you play it just right.

Oh, and many of the graphics and palettes have changed, which is a nice touch.

If you like Balloon Fight, give this one a try!
(If you haven’t played Balloon Fight, it’s a lot like Joust).
